When should I use CNC machining versus Rapid Molding?

Before making the investment to have injection-mold tooling made or high-volume machining processes, you likely will want to test a part that is as close to the production part as possible. CNC machining is the best option for this situation.   Additionally, engineers often need just one or maybe a few parts for test fixtures, assembly jigs, or assembly fixtures. Machining is the best option here as well, but traditional machine shops often charge a significant non-recurring engineering (NRE) charge for programming and fixturing. This NRE charge often makes getting very small quantities not affordable. The automated CNC machining process eliminates the upfront NRE costs and is able to offer quantities as low as one part at an affordable price and get parts in your hands in as fast as 1 day.
